The Sporlan KT-12-AL thermostatic expansion valve is a KT-12 series TXV designed for ammonia (R-717) refrigeration systems. This AL variant includes a 10-foot sensing element, enabling longer capillary runs between the valve and sensor and accommodating larger evaporator configurations. In industrial ammonia applications, it meters refrigerant into the evaporator to regulate evaporator superheat and maintain stable operating conditions. The KT-12 family is a standard Sporlan TXV line used in R-717 installations, and the AL designation identifies a specific configured variant within that family.
